IMPROVED PURNAGES FOR HOT-AIB. BLAST.
TO ALL WHOM IT MAY CON CERN Be it known that I, RICHARD LONG, of Chillicothe, in the county of Ross., and State of Ohio, haveinvented Va new and improved Furnace Hot-Air Blast; .and I do hereby declare that the following is a full, clear, and
exact description thereof, which will enable those skilled in theart to make and use the same, reference being had to the accompanying dranrings, forming part o'f this specification.
This invention relates to a new and improved method of constructing and arranging the air-pipe for heating the air-blast for furnaces for smelting. and reducing the ores in the manufacture oiron, having particular reference to the materials of which the nir-pipe is formed, the method of itsconstruction, and also to the materials and method of construction of the supporting walls; and'tlie invention consists mainly in making the air-pipe of {ire-clay, and of an oval form, and inl uniting the sections of which the pipe isA composed by socket-joints clamped and keyed together, whereby leakageis prevented, land expansion and' qbntraction are provided for, and the apparatus rendered veihcient and durable, as will be hereinafter ,more fully described.
Figure 1 represents an end elevation of the air-pipe supported` by suitable Walls, with the outside casing removed. i
Figure 2 is a horizontal section 'of theapparatus, showing the columns which support Vthe vchimntay-stack, and the Walls which support the air-pipe, the section being through the line-y y of fig. 1.
Figure 3 is a vertical sectional elevation, the section being on the line a; a: ofg. 1.
Similar letters of reference indicate corresponding parts. i i
This apparatus is placed near the furnace-stack, and the heat discharged from the top of the stack `in the process of smelting ores `is conveyed into this apparatus beneath the air-pipe, passing upwards through and between the sections of the pipe into the chimney which is built upon it and supported by it, so'that the blast is heated by the combustible and burning-gases which escape from the stack. Utilizing this heat for this and other purposes is by no means ner: with me. Steam is generated by it for blowing the blast as well asheating it in many establishments.
In arrangements of this kind heretofore used, the heating or blast-pipe and the supporting walls have been made of iron, and being subject to constant expansion and contraction, they soon become cracked and unfit for use. By making the pipe of {ire-clay and the supporting walls of fire-brick and plates of metal, I overcome all objections in consequence of expansion and contraction, and render the apparatus durable and not liable to get out of order.
Referring to the drawing, A represents the blast-pipe, B the supporting walls. C represents the main supporting pillars for the chimney, which are of iron. The air-pipe and the supportingwalls are enclosed by a casing, marked D, which may be either metal or masonry. To the pillars C, doors E lare hinged, to give access to the interior upon each side, as seen in the drawing. As seen, the form ofthe air-pipe is oval, the advantage of which form is that it affords less surface for ashes to rest upon than a ound pipe would. The ashes being a Vnon-conductor, interfere materially with the heating of the blast when resting upon the pipe. The pipe is made in sections, which are united by semicircular pipes or rmove-necks, and the joint, (as seen at F, fig. 3,) is a socket-joint, the flanges being united by clamps and keys, as seen infig. 1 at g. The pipe passes andre-passes back and forth in a winding or sinuous form in layers or tiers, connected together by the semicircular pipes, as seen in iig. 1. The interior of the pipe forms a continuous channel for the air, unbroken by any angles or corners. The air enters the lower-tier at At, and after passing through the pipe is discharged at J, from whencc it is conducted to near the bottom of the stack in the usual manner. The supporting walls are made of (ire-brick, which are ttcd to the pipe, cach tier of Abricks having an iron plate, marked f, which separates the tiers or courses of brick, as seen in-thc drawing. 1t will thus be seen that all thc parts which are exposed to the more intense heat from the iiame of the burning gases are constructed of {ire-clay and lire-brick, and so arranged that the expansion and contraction by the variations of temperature do not injure or affect them. Beneath the airpipe A there is a plate, marked H, which rests on cleats When the heater is in operation, an open or perforated plate is employed to check and spread the flame, thereby diffusing it more uniformly under the pipe. In cases of accident or stoppages for temporary repairs outside the heater, a solid plate may be employed to close tho space beneath the pipe entirely, for the purpose'oi` retaining the heat and excluding the cold air. On thc top of the apparatusthere is another check-plate, G, upon which the chimney rests, the orifice through which is so contracted that the heat is retarded around the pipe, and not allowed to have a. free dischargeinto the chimney,
as is usual: A
I claim as new, and desire to secure by Letters Patent- 1. Constructingl the air-pipe of a furnace-blast heater of fire-clay, 'substantially :1s described;
2. Constructing the air-pipe of an oval or other equivalent form, and' unit-ing the sections of which it is composed by socket-joints, with clamps and keys, substantially as shown and described.
4. Placing an open or solid plate beneath the :tir-pipo, substantially as and for the purpo sesherein described.
The above specication of my invention signed by me, this 7th day of October, 1867.
